All the statutory authorities accepted BIS Codes as the standard norms, which had a good amount of reasoning and logic to arrive at the fire water pumping capacity requirement for a large complex having several plants.
The current law stipulates that in a complex catered by a fire water network, the pumping capacity requirement should be arrived at by considering two largest simultaneous demand plot areas @1 lpm /M2 with 50%standby pumping requirement and the remnant pressure at the remotest area in that network should be at least 7 kg/cm2 g. For plot area measurement, the fire break condition of at least 15 M apply.
At that time in 2010, that gave me a big relief.Discussed that idea with Dilip Koimattur , TechnoFire director&ex-TAC officer and he concurred that idea instantly.Immediately I shared the same with M/S Kiran Shinde and Kirit Brahmabhatt. Both of them okay ed the same as long as the concerned statutory authority approve. That ensured that South plot of the main refinery beyond 9th street Southwards in DTA plot shall be serviced with fire water from original DTA fire water pump house 713. Immediately I asked M/S Bechtel/MEC / and TechnoFire to carry out the initial check of hydraulics assuming the network periphery will be of 42" diameter. To our good fortune, it was coming to about 8-8.2 Kg/cm2 g which relieved us completely. There I have to specifically mention the important contribution of Mr Anthony Mankodi of MEC. He suggested that the linear length of parallel headers from existing pump house to DTA Gasification Complex B/L being about 4 Kms each long, it is better to make provision for cross breeders in the underground headers going to gasification complex B/L. That idea was welcomed by one and all and implemented.
As the J3 project execution start was getting delayed, sometime in August 2010, SM asked me to carry out an audit of the Fire Prevention System of all Reliance manufacturing locations excepting Jamnagar. For carrying out that audit, I formed a core team of members drawn from OSBL project group for fire water system/network and core instrumentation manpower for Fire&Gas system.
The OSBL team led by M/S Sriram and Madhu Narayanan took care of auditing existing fire water pumping, overall network both in offsite as well as respective plant ISBL, quantity of throw and reach of the hydrants and monitors all across. I personally looked into the respective plant /complex original design basis and available hydraulic analysis calculations of complex network.
The instrument team led by Mr.Upendra Joshi took care of auditing Fire&Gas system as well as the deluge arrangement & the fire water pump start sequence logic etc.
